The invention is designed mainly for cotton mill machinery andparticularly for roving frames to insure safety and guard againstaccidents when machinery is running.

The invention relates to machinery and including enclosed gearing and ashipper rod for starting and stopping the machinery. The inventioncontemplates a latch member mounted upon the shipperrod to movetherewith and engageable with a fixed part to secure the shipper rodagainst movement when occupying a position with the machinery at restand out of action.

The invention furthermore provides fastening means for the closure,which controls access to the box, housing or casing containing thegearing, to prevent opening thereof when the machinery is running, saidfastening means being mounted upon the frame, or like supporting part,and connected with the shipper rod to be actuated thereby to release theclosure when the machinery is at rest and to secure the closure when themachinery is in motion according to the position of the shipper rod.

While the drawings illustrate a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand requirements, the design may be varied and such other changes in theminor details of construction may be resorted to within the scope of theinven tion, as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and the drawingshereto attached, in which Figure 1 is a side view of safety meansembodying the invention, showing the same applied to a roving frame, thefull lines showing the shipper rod locked and the closure to the gearcasing released and the dotted lines showing the closure to the gearcasing locked and the shipper rod moved to throw the machinery inaction.

-toin the following description and designated in the several Views ofthe drawings by like reference characters.

The numeral 1 denotes a roving frame and 2 the closure to the gearcasing or box which contains the twist and builder motion gearing. Thenumeral 3 designates the usual shipper rod for throwing the operatingmechanism into and out of gear.

The numerals 4 and 5 designate fixed bearings in which the shipper rod 3is These parts are of well known construction and arrangement, and areillustrated to demonstrate the application of the invention, and arerepresentative of equivalent parts in other machinery including ashipper member and a closure requiring to be made secure when themachine is in action. i

The safety means includes a pivoted latch member embodying anarm 6 and anose 7 at the swinging end of the arm 6 and adapt ed to engage thebearing l and secure the shipper rod 3 against movement when the frameis out of action or not running. The

nose 7 is depressed to embrace the upper portion of the rod 3 andprevent lateral displacement of the free end of the arm Gwhen the latteris in operative position. The latch member is pivoted to a post 8 whichis mounted upon the shipper rod 3 and se- A clamp screw 9 threaded intothe post 8 bindingly engages the rod 3 at its inner end to secure thepost to the rod in the required adjusted position. lVhen the shipper rod3 ismoved to the left to the limit of its throw, the machinery of theroving frame is thrown out of action, and this brings the safety meansinto position so that when the latch member is thrown forwardly anddownwardly its nose 7 engages the rod 3 in front of the bearings 4, withthe result that the shipper rod is prevented from being accidentallymoved towards the right to throw the machinery in gear, thereby avoidingan accident should one be oiling or adjusting the gearing located withinthe box or casing 1. V

The fastening means for the closure 2 is pivotally mounted upon theframe 1 and is adapted to be automatically operated by the shipper rod3. The numeral denotes a plate, which is bolted or otherwise secured tothe frame 1 and formed with sleeve 11, in which is mounted a journal 12formed at one end of an arm 13. A longitudinal slot 14- is provided inthe end portion of the arm 13 and receives a screw 15 or like partapplied to the post 8. Longitudinal movement of the shipper rod 3effects a pivotal movement of the arm 13, the journal 12 of whichrotates in the sleeve or bearing 11. An extension 16 projects laterallyfrom the outer end of the journal 12 in an opposite direction to the arn 13. A member 17 projects laterally from the extension 16 andterminates in an offset portion 18 which is adapted to project acrossthe part of the closure 2 and prevent its opening when the frame ormachinery is running, as indicated most clearly by the dotted lines inFigure 1 of the drawings. When the shipper rod 3 is thrown to the rightthe fastening means is simultaneously operated to prevent opening of theclosure 2. hen the shipper rod 3 is moved to the left to throw themachinery out of action the fastening means is simultaneously actuatedto release the closure 2 and admit of access to the gear casing or box1, for any desired purpose, and to prevent accidental movement of theshipper rod it is heldby operating the latch member to cause the hose 7thereof to engage i the bearing 4,,as indicated most clearly in Figure lof the drawings.

Having thus described the invention, we claim:

1. The combination with a shipper rod and a bearing therefor, of a postadapted to be secured to the shipper rod in an adjusted position, and alatch member pivoted to the post and including a nose to engage the saidbearing and rest upon the shipper rod and prevent movement thereof inone direction.

2. The combination with a gear box closure, a shipper rod and a bearingtherefor, of a post adjustably secured to the shipper rod, a latchmember pivoted to the post and adapted to engage the said bearing of theshipper rod, and fastening means pivotally mounted intermediate itsends, and having one end adapted to secure the said gear box closure,and having the opposite end slidably connected with the said post.

3. In combination with the closure of a machine casing and shipper rodfor throwmovement, there being a slot in the other end of said arm, apost on said shipper rod having pin engaging in said slot for rockingsaid arm, a latch pivoted on sa1d post,

and a bearing on said machine frame for the shipper rod forming a stopfor engaging the latch and preventin accidental movement of the shipperrod to operate the machine when said arm is disengaged from saidclosure.

In testimony whereof we aflix our signatures.
